The machine includes a tilter articulated with the chassis around one tilting axis oriented transversely to the longitudinal direction, and in the transport position of the side units, each tool unit is closer to the median plane than the respective arm.

An agricultural machine comprising a connecting structure designed to be laterally mounted to a tractor, the connecting structure including a coupling support, a carrier beam and a transmission unit; the transmission unit including a driving pulley, a driven pulley, a transmission element drive-mounted on the driving and driven pulleys; a work unit articulated to the carrier beam via at least one folding axis, the work unit being fitted with at least one work tool configured to be driven in rotation from the transmission unit. In this machine, the folding axis and the rotation axis of the driven pulley are separate from each other.

An agricultural machine including a connecting structure designed to be hitched to a tractor, the connecting structure including a coupling support, a carrier beam and a transmission unit; the transmission unit including a driving pulley, a driven pulley, a transmission element drive-mounted on the driving and driven pulleys, the transmission unit including a transmission element tensioning system; a work unit articulated to the carrier beam via at least one folding axis, the work unit being fitted with at least one work tool, which is driven in rotation. In this machine, the tensioning system applies an unfolding force to the work unit during at least one part of the deployment from a transport position.

An agricultural implement having a main chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms being provided with operating elements remote from the support structure, the support structure defining a working width between the operating elements and the main chassis member, and the support arms being adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. In a headland position the support arms are adjustable such that a distance between the operating elements and the main chassis member is less than the minimum working width.

An agricultural implement including a central chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms having operating elements defining a working width between the operating elements and the main chassis member. The support arms are adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. A first stop defines the position of the minimum working width and a second stop arranged vertically with respect to the first stop retains the support arm in the transport position when the distance between the operating elements and the main chassis member is less than the minimum working width.

An implement includes an implement frame having an integrated elongate toolbar carrying at least one row unit, at least one wheel coupled to the implement frame and defining an axis of rotation, a sensor configured to sense a position of the at least one row unit relative to the ground, and a control system. The control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause a lift system to raise or lower a portion of the implement frame connected to the lift system to rotate the implement frame about the axis of rotation of the at least one wheel based at least in part on the signal. Control systems and related methods are also disclosed.

row crop heads and pivoting assemblies associated with the row crop heads operable to displace a crop divider of the row crop heads during folding of a portion of the row crop head are disclosed. In some implementations, a pivoting assembly may include a first bracket coupled to a center frame of a row crop head, a second bracket coupled to a wing frame of the row crop head, and a rotatable locking component rotatably coupled to the first bracket. The rotatable locking component is operable to lock a row divider disposed at an interface between the wing frame and the center frame when the wing frame is moved from an unfolded position to a folded position relative to the center frame.
